摘要：

The information from the central drift chamber of the H1 experiment is used in a first level trigger to find and count charged tracks, originating from genuine ep collisions at the HERA storage ring. Background processes, predominantly from beam-wall and beam-gas interactions, are discriminated because their distance of closest approach to the collision vertex differs from good events. The track finder is designed in a pipelined fashion, producing decisions at the bunch crossing frequency of f(b) = 10.4 MHz, however delayed by a fixed decision time of 2.3 mus. This operation is deadtime free but still uniquely related to the specific bunch crossing 24 cycles earlier. The hardware implementation relies on XILINX logic cell arrays which are programmable providing a high flexibility.
